Shock-absorbing mechanism of motor bearing

Abstract

The invention at least consists of a hollow beam barrel, an axle center and a damping component. A flute is set at bottom in axle barrel, and the flute has a convex. A bearing with through hole is set in beam barrel. The damping component is set on the convex in flute, and between the damping component and the flute a buffer space is formed. The axle center is pin joint in beam barrel, and touches the damping component. When axle center rotates, by support of damping component, the damping component reduces the shock generated from rotation.

Description

technical field [0001] The invention relates to an anti-vibration mechanism of a motor bearing, in particular to an anti-vibration mechanism for reducing shaking or vibration generated when the motor is running. Background technique [0002] Please refer to the traditional motor axis support structure shown in Fig. 1 and Fig. 2. As shown in the figure, it at least includes a fan frame 11, and at least one support seat 12 is formed in the fan frame 11, and a support seat 12 is formed on the support seat 12. Hollow shaft tube 121, at least one bearing 13 and one shaft center 14 are arranged in the shaft tube 121, one end of the shaft center 14 passes through the bearing 13 to be pivoted on the support seat 12, and the other end of the shaft center 14 is connected to a fan wheel 15 , and the shaft 14 has a neck 141 through one end of the bearing 13, so that a buckle 16 is fastened, and the bearing 13 is interfered by the buckle 16 to prevent the shaft 14 from running At the ti...

[0002] Please refer to the traditional motor axis support structure shown in Fig. 1 and Fig. 2. As shown in the figure, it at least includes a fan frame 11, and at least one support seat 12 is formed in the fan frame 11, and a support seat 12 is formed on the support seat 12. Hollow shaft tube 121, at least one bearing 13 and one shaft center 14 are arranged in the shaft tube 121, one end of the shaft center 14 passes through the bearing 13 to be pivoted on the support seat 12, and the other end of the shaft center 14 is connected to a fan wheel 15 , and the shaft 14 has a neck 141 through one end of the bearing 13, so that a buckle 16 is fastened, and the bearing 13 is interfered by the buckle 16 to prevent the shaft 14 from running At the time, it will come out from the shaft tube 121, and the bottom of the shaft tube 121 is provided with a wear-resistant pad 17 to make one end of the shaft center 14 touch, and reduce the friction force when the shaft center 14 is running; When the shaft 14 rotates in the bearing 13, the internal clearance of the bearing 13 will cause the shaft 14 to shake; and when the shaft 14 rotates, it will be affected by external disturbances such as: airflow resistance and the weight of the shaft. , and the shaft 14 will also vibrate at different rotation speeds, which will greatly increase the disadvantages of vibration and abnormal noise generated during operation
